LightStim: A Framework for QEC Protocol Evaluation and Prototyping with Automated DEM Construction
Xiang Fang, Ming Wang, Yue Wu +6
Fault-tolerant quantum computing increasingly demands rigorous, circuit-level evaluation of diverse quantum error correction (QEC) protocols and efficient prototyping of new ones.…
Bridging Superconducting and Neutral-Atom Platforms for Efficient Fault-Tolerant Quantum Architectures
Xiang Fang, Jixuan Ruan, Sharanya Prabhu +4
The transition to the fault-tolerant era exposes the limitations of homogeneous quantum systems, where no single qubit modality simultaneously offers optimal operation speed, conne…
TrapSIMD: SIMD-Aware Compiler Optimization for 2D Trapped-Ion Quantum Machines
Jixuan Ruan, Hezi Zhang, Xiang Fang +8
Modular trapped-ion (TI) architectures offer a scalable quantum computing (QC) platform, with native transport behaviors that closely resemble the Single Instruction Multiple Data…
iSwitch: QEC on Demand via In-Situ Encoding of Bare Qubits for Ion Trap Architectures
Keyi Yin, Xiang Fang, Zhuo Chen +10
Recent advances in quantum hardware and error correction have paved the way for early fault-tolerant (EFT) quantum computing. We propose iSwitch, a hybrid system architecture for t…
Towards LLM-based optimization compilers. Can LLMs learn how to apply a single peephole optimization? Reasoning is all LLMs need!
Xiangxin Fang, Lev Mukhanov
Large Language Models (LLMs) have demonstrated great potential in various language processing tasks, and recent studies have explored their application in compiler optimizations. H…
